Overview
- Provisional data from late September put the 12‑month euribor at about 3.243%, its highest level since mid‑2024 and up roughly one percentage point over the past year.
- If confirmed by the Bank of Spain on October 1, the rise will feed directly into variable‑rate mortgage reviews and push many monthly payments higher.
- Comparators estimate the impact for a typical 150,000€ mortgage over 25 years with a 1% spread: annual reviews could cost about 84–88€ more per month (≈1,010–1,054€ a year).
- Households with semiannual reviews also face increases, with models showing roughly 55€ extra per month on the same mortgage when the index is applied to a six‑month revision.
- Analysts link the jump to higher inflation driven by energy prices, recent conflict in the Middle East and market expectations that the European Central Bank will keep raising official rates, which could prolong pressure on households with variable debt.
